“…Tuber samples were collected each month from 8 -12 mo after planting (MAP) for cassava and arrowroot, 8 MAP for yam and taro, and 3 -4 MAP for sweet potato with a uniform interval. Tubers were harvested at different periods based on their maturity (Vimala and Hariprakash 2011;Nzola et al 2021) (Wicklow, Ireland).…”

Based in the Visayas State University, Philippines, the germplasm collection of the Philippine Root Crops Research and Training Center (PhilRootcrops) is home to several varieties that have not been fully characterized for their potential use in the production of functional foods. This study evaluated the compositional properties, amylose/amylopectin ratio, and glycemic index of flour and starches of 10 varieties of cassava (Manihot esculenta Crantz), sweet potato (Ipomoea batatas L. (Lam)), and taro (Colocasia esculenta L. Schott); 8 varieties of yam (Dioscorea alata L.); and 5 varieties of arrowroot (Maranta arundinacea L.), which was the recommended varieties of the National Seed and Industry Council (NSIC). The total starch as well as the amylose/amylopectin ratio of the starch component was determined using Megazyme assay kits, and the glycemic indices were predicted through enzymatic in vitro starch hydrolysis. Results revealed significant (p < 0.05) varietal variations on flour and starch yield, dry matter, crude protein, crude fiber, amylose/amylopectin ratio, and glycemic index. Among these crops, sweet potato was found to have the highest amylose contents, while taro and arrowroot showed lower glycemic indices. These profiles can serve as fundamental information for processors to develop new products that capitalize on these unique properties.

“…After processing, the quantity of gari obtained from cassava (gari yield) is of utmost economic importance to farmers and processors. Gari yield determines processors' profit and future demand for any newly released cassava variety for gari production [10,20]. The lower gari yields of biofortified varieties when compared to that of white root check variety can be explained by the submission of Duah [43] who noted that yellow root cassava varieties tend to yield lower quantity of gariin comparison to conventional white cultivars due to their lower dry matter content.…”

“…In Nigeria, about 160 million of the country's residents eat cassava in diverse forms at least once a day [8,9]. This drought tolerant crop can also be stored in the ground and harvested when needed thereby providing households with an alternative when the harvest of other crops fails [10]. The high level of dependence of farming families and several Nigerians on cassava and its products makes them vulnerable to vitamin A deficiency (VAD).…”

Bio-fortification of cassava increased its total carotenoid content (TCC) but may have boomerang effect on key quality traits of cassava like dry matter content (DMC). Meanwhile, DMC of cassava reflects its true biological and product yield. Therefore, this study was conducted to determine the relationship between TCC of some novel yellow root cassava varieties (YRCVs) and each of DMC and gari yield. Three bio-fortified YRCVs (TMSI010593, TMSI011368 and TMSI010539) and a white root variety (TMSI30572) as check were harvested 12 months after planting. The TCC (µg/g) and DMC (%) of the fresh storage roots were determined following standard procedures. Subsequently, the fresh storage roots were processed into gari and gari yield (t/ha) was estimated. Data collected were subjected to descriptive statistics, analysis of variance at 5% level of probability and correlation analysis. The check variety lacked TCC but had significantly higher DMC (34.34%) and gari yield (3.40 t/ha) than other varieties except variety TMSI010593 for DMC (33.95%). Total carotenoid content of the bio-fortified cassava varieties ranged between 7.81 µg/g (TMSI011368) and 10.23 µg/g (TMSI010593). Among the YRCVs, TMSI010593 consistently had the highest DMC (33.95%) and gari yield (3.2 t/ha) whileTMSI010539 had least values of 24.63% and 2.2 t/ha, respectively. The TCC of the fresh storage roots correlated negatively with DMC (-0.22) and gari yield (-0.22). Notably, TMSI010593 had a good combination of high TCC, DMC and gari yield, hence, it can deliver high gari yield and TCC to processors and consumers, respectively. Propagation of variety TMSI010593 is therefore encouraged because it can offer the triple benefits of food, nutritional and financial security.

“…The accumulation characteristics of starch in cassava can directly affect the yield, starch content and maturation of cassava storage roots [ 4 ]. The raw material for starch synthesis in the roots is mainly derived from photosynthesis products in the source leaves, which are transported through the stem phloem to the roots and then degraded and utilized for starch synthesis [ 5 ].…”

Background Cassava (Manihot esculenta Crantz) is an important multiuse crop grown for economic and energy purposes. Its vegetative organs are storage roots, in which the main storage material is starch. The accumulation characteristics of starch in cassava roots can directly affect the yield, starch content and maturation of cassava storage roots. In this study, we used a cassava sexual tetraploid (ST), which showed early maturation heterosis in previous work, as the main test material. We analyzed the sucrose metabolism and starch accumulation characteristics of the ST and its parents from the leaf “source” to the storage root “sink” during different developmental stages and explored the regulatory mechanisms of ST storage root early maturation by combining the transcriptome data of the storage roots during the expansion period. Results The results showed that the trends in sucrose, glucose and fructose contents in the ST leaves were similar to those of the two parents during different stages of development, but the trends in the ST storage roots were significantly different from those of their parents, which showed high sucrose utilization rates during the early stage of development and decreased utilization capacity in the late developmental stage. Transcriptome data showed that the genes that were expressed differentially between ST and its parents were mainly involved in the degradation and utilization of sucrose in the storage roots, and four key enzyme genes were significantly upregulated (Invertase MeNINV8/MeVINV3, Sucrose synthase MeSuSy2, Hexokinase MeHXK2), while the expressions of key enzyme genes involved in starch synthesis were not significantly different. Conclusions The results revealed that the pattern of sucrose degradation and utilization in the cassava ST was different from that of its parents and promoted early maturation in its tuberous roots. Starch accumulation in the ST from sucrose mainly occurred during the early expansion stage of the storage roots, and the starch content during this period was higher than that of both parents, mainly due to the regulation of invertase and hexokinase activities during sucrose metabolism. This study provides a basis for further genetic improvements to cassava traits and for breeding varieties that mature early and are adapted well to provide starch supply requirements.
